This is an educational development oriented to learn microprocessor programming and analog techniques of signal treatment. It hasn't a commercial use but is a very educative project (See Electronics Section)

6 m Transverter

Finally I have found a transverter that seems work in 6 meter band. Be patient, I am building it, wait a couple of weeks to see the results. But now you can read the original article.

Adventures in RTTY

Several years ago, before packet radio I got two mechanical Teletypes. Put the in service was an incredible adventure that I am still writing be patient.

 

Subwoofer Amplifier

The audio and acoustic systems are quite interesting. Although my Home Theater hasn't a power subwoofer amplifier  has a low power output  so I am building a ported box and a power amplifier. To see the state of the project see Electronics section.
